I've had to rip back once and tink back a couple of times. And this delicate laceweight cashmere is holding up wonderfully. The kit contains a 50 gm ball of yarn. One of the pattern notes reminds us to weigh the yarn after 14 repeats. If we're near 25 gms, then skip the one repeat without any increases and head straight into the decreases.
Well, I borrowed a friend's scale at knitting the other night. And after my 14 repeats, I actually had 33 gms of yarn left. And while I do know that each repeat uses a different amount of yarn because the stitch count differs, I still averaged it out. Each repeat used 1.21 gms of yarn. And here is where I decided to live dangerously! (cue ominous music here - theme from Jaws maybe?) I am taking a chance and knitting three repeats even before I start the decreases. Going on the assumption that math is my friend..... 1.25 gms of yarn per repeat x 33 repeats = 41.25 gms. Hopefully that is enough to give me a slightly larger scarf and not run out of yarn one repeat before binding off!
